Battery switching method, method and device for sending battery switching signal

Abstract

The invention discloses a battery switching method, a method and a device for sending a battery switching signal, wherein the battery switching method includes: receiving a signal corresponding to a predetermined temperature output by BMS analog, wherein the predetermined temperature is output when the battery to be switched is switched The temperature corresponding to the voltage; perform temperature compensation on the constant current source circuit according to the signal corresponding to the predetermined temperature, so as to adjust the output voltage of the constant current source circuit to a preset value, and realize the switching operation between the current power supply battery and the battery to be switched. By using the present invention, the seamless switching operation between the current power supply battery and the battery to be switched can be successfully completed. This method does not require any improvement on the DC power supply system, the switching efficiency is high, and the system performance is greatly improved, which solves the problem of the existing technology It is necessary to modify, upgrade or debug the DC power supply system before it can interact with the BMS. The upgrading and debugging processes are complex and require a large amount of engineering, which results in high implementation costs.

Description

technical field [0001] The invention relates to the communication field, in particular to a battery switching method, a method and a device for sending a battery switching signal.
